Context of Lesson:
This will be the first lesson in the unit on covalent bonding and molecular geometry which will because after the unit on ionic bonding. The students will already have some knowledge of bonding through what they learned during the ionic bonding unit; with that knowledge and the new knowledge they will be gaining the students will be able to understand covalent bonding and the molecular geometry of molecules. In this lesson the students will be getting an introduction to the unit on covalent bonding and molecular geometry. During this lesson the students will be filling out a KWL worksheet on the shapes and properties of molecules.
How long are your periods?
I have 50 minute periods. Opportunities to Learn: Depth of Knowledge:
Level 1
Identify the number of elements in a compound.
Identify characteristics of ionic and molecular compounds.
Level 3
Differentiate between the melting and boiling points of ionic verses molecular compounds.
Prerequisite Knowledge:
Ionic bonding
Physical change
Atomic properties
Molecular formulas
Nomenclature
Periodic Table
Plans for Differentiating Instruction:
This class is basically a review of some of the topics that we will be needing to cover this new unit on covalent bonding. The first part of class the students are filling out a KWL which all students will be able to do because there are no right or wrong answers. We will then discuss some differences between ionic and molecular compounds verbally but also with examples in real life so that students can visualize the differences.
Accommodations and modifications:
This class is basically going to be a review. During the end of the class when I give the students more examples to work on I can give some of the struggling students a sheet which has some rules to nomenclature and molecular formulas. I will also go to those students when I am walking around and make sure that they are understanding the material.
Environmental factors:
The students will be sitting in groups of four like they would normally do during the semester.
Students will differentiate between the melting and boiling points of ionic verses molecular compounds.
Students will identify the number of elements in a compound.
Students be able to explain the differences between ionic and molecular compounds?
Students will identify the characteristics of ionic and molecular compounds.
Instruction: Opening:
Activate Prior Knowledge of bonding
Have students start a KWL worksheet
Students will be asked to fill out the first two columns.
What you know and what you want to learn.
It is a simple concept that will help me to teach.
The concepts that you know I will not have to go into much detail and the concepts that you want to know I can spend more time on. It helps me so that I don't waste time teaching about something you already know about.
Are they familiar with KWLs? If not, how will you explain their purpose?
Where is worksheet?
You should write the instructions you will give?
How will they know what to do while you're taking roll?
Engagement:
What are some differences between ionic and molecular compounds?
Students will ponder that question for a few minutes thinking about responses.
I will then get the responses from students and write them on the board, noting which ones we will be talking about.
If they are getting close to some I will try to get them to think of them.
Is this a question for your students? Will you lead this discussion? If so, how will you record/organize their answers?
Many ionic compounds are solids at room temperature.
Many molecular/covalent compounds are liquids or gases at room temperature.
Have examples in the classroom to show.
Salt, Water, Air, etc.
How do these connect to melting and boiling points?
Review molecular formulas and nomenclature.
What do the subscripts and coefficients mean?
Review sheet to be completed in groups.
They will have already done nomenclature and molecular formulas so this should be very easy.
The students will need to know the nomenclature and molecular formulas in order to complete worksheets and understand the structures of molecules. Many questions will be given that ask for the types of bonds or structure of a named compound.
What does this have to do with covalent bonds?
Closure:
Outline what we did in class and what to expect in the next class.
There are more types of bonds than the previously learned ionic bonds.
We saw that in ionic bonds one element donates or accepts an electron(s) so that it follows the octet rule.
Can we think of other ways that an element can do this?
We will discuss some of these ways tomorrow, such as sharing of electrons.
We will not go back to the KWL till the end of the unit.
What will you say?
Are you planning to return to the KWL sheet?
Assessment:
I will formatively assess my students understanding by questioning. Good. What questions will you ask?
What are some properties of ionic compounds?
What are some properties of molecular compounds?
Which type of compound ionic or molecular has a higher boiling point?
